I'd love to know that too. Good spotting if they did. If they didn't, they still look lovely.

BTW I think that is one of the clearest photographs of Victoria's engagement and wedding ring I think I have seen. They are wonderfully understated and elegant. Definitely of the "less is more" variety!

Another question: Is it also common practice to wear the rings on the left hand, or is this a modern trend?

It's the oldest 'trend' imaginable, because the left ring finger has been considered to be directly connected to the heart since the ancient Egypts.
In Europe, only a few countries (like Germany and Norway, I believe) have the tradition to wear the wedding ring on the right hand, in most other countries it's worn to the left and thus 'close to the heart'.
